More-advanced features include Bluetooth, voice dialing, a voice recorder, and A-GPS. The phone also supports e-mail and instant messaging, but you need to download those applications from the MetroPCS store. Even though the M750 is a touch-screen device, its browser is just simple Access Netfont WAP 2.0 instead of full HTML. This was a little disappointing, but since the M750 lacks an accelerometer, the M750 probably isn't the best platform for a HTML browser anyway.
The M750 has a simple music player interface. Settings include shuffle and repeat modes, four equalizer presets, and the capability to create and edit playlists. You need to have a microSD card to use the music player. The M750 has an internal memory of 77MB, and supports up to 4GB cards.
The 1.3-megapixel camera on the M750 produces surprisingly good photo quality. Images looked sharp and the colors are bright without looking washed out. You can take pictures in four resolutions and three quality settings. Other settings include a night mode, a self-timer, multishot mode, four color effects, four fun frames, and the choice of two shutter sounds plus a silent option. There is no built-in video recorder.
You can personalize the M750 with a variety of wallpaper and ringtones, plus you can download more from the MetroPCS store.
Performance
We tested the Huawei M750 in San Francisco using MetroPCS' network. Call quality was decent, but it could be better. On our end, we heard our callers very clearly and experienced little static. Their voices sounded natural as well. On their end, they could hear us loud and clear. They did detect quite a bit of background noise at times, however, and there was a bit of crackling. Speakerphone calls were mediocre at best. Though we could hear callers fine, they said we sounded muffled and distant, even though we spoke relatively close to the mic. Music quality via the speakers sounded tinny and hollow, and we would recommend using a stereo headset for the best performance.
The M750 supports only 2.5 1xRTT networks, but since it has only a WAP browser, we thought that was fine. Simple WAP pages loaded in around 30 seconds.
The M750 has a rated battery life of 6 hours talk time and 11.25 days standby time. It has a tested talk time of 6.72 hours. According to the FCC, the M750 has a digital SAR rating of 1.14 watts per kilogram.
